Abstract

A multiconfigurational paired excitation SCF (MC PE SCF) framework is described, in an attempt to generalize Veillard and Clementi's MC SCF theory. It is shown that a MC PE wavefunction can give a set of diagonal. Fock operators entering the variational Euler equations and, as a consequence, a recently described coupling operator technique can be used to solve the Hartee-Fock problem in this case. Monoconfigurational open or closed shells can be solved in the MC PE approach by means of a unique computational algorithm. © 1977.
